Be it known that'I, HANS SATHER, a citizen of the United States, residing at St. Paul',in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Grain-Doors for Cars, of which the following is a. specification.

My invention relates to improvements in grain doorsfor cars, its object being to providea door which is particularly strong and durable and which is so'hung within the car as tobe easily movable upon its supports into the car and away from the door openingQits object being further to provide means in connection with the door to cooperate with th'esides of the door opening andprevent the door swinging therethrough, together with locking means to allow the door to be securely locked in the door opening while it is-being held from swinging therethrough.

To this end my invention consists in the features of construction and combination hereinafter particularly described and claimed.

In the accompanying drawings showing an embodiment of my invention, Figurel is a side elevation of a grain car shown partly broken away and fitted with my improved door; Fig. 2 is a top view of the same broken away to show the door supporting parts; Fig. 3 is an outer view of the door with the outside plate removed, and showing the looking parts in position to lock the door in the door opening; Fig. 4 is a view corresponding to Fig. 3 with the locking parts in position to hold the door freed from the sides of the door opening; and Fig. 5 is a detail view of a locking cam forming part of the invention with the actuating handle therefor removed.

In the drawings A represents a grain car of ordinary construction and 2 the side posts of the ordinary door opening.

B represents my improved grain door having pivotal support through the medium of the rod 3, said rod being secured at itsouter end as by thepin l in the upper end of a bar 5 slidably supported upon-the outer face of the door, the outer end'of'the rod extending through a vertically slotted opening 6 in the door. The rod at its rear end extends slidably and rotatably through a sleeve 7 carried by a bracket O. The bracket C has slidable support upon horizontal rails 8 mounted inside the car by means of rollers Specification of Letters Patent.

Patented Jan. 16, 1917.

Application filed September 18, 1915. Serial No. 51,491;

9 journaledin-the'upper end of the bracket and traveling upon the tops of the rails, and rollers 10 journaled in the bracket below the rails and traveling against the under faces thereof. A nut 11 is preferably threaded upon the inner end of the rod 3 to prevent the door being pulled away from the bracket, the doorbeing removable from the bracket when'the nut is unscrewed; v

By m'eans of the above described rotatable and slidable support for the door in the, bracket the: door may be moved into or out of thedoorway, and when inside the car may be shoved along the rails Saway from the door opening; When outside thecar the door maybe swung away from-the door opening and supported upon the bracket 12 secured on the outside of the car at one side of the door opening.

In orderto lock the door within the door opening I provide the following described features. Thelower end of the bar 5' has pivotalconnection 13 to one-side edge of a plate 14:, said plate being centrally secured upon a shaft 15' journaled in the door. The outer end of the shaft is squared to receive an actuating handle 16. Horizontally disposed bars 17, and- 17 have pivotal connec tion 18 and 18 attheir inner ends with the upper" and lower edges of the plate 14, the pivotal connection 18 being to the left of the center of the plate and the pivotal'connection 1 8 being to the right of the center of the plate. The bars 17 and 17 at their outer ends carry upright arms 19 and 19 slidable upon the outer face of the door. The arms 19 and 19 carry pins 20 and'20 projecting outwardly slidably through the out-turned edges 21 and 21 of the door. The arms 19 and 19 also support locking plates 22 and 22 upon the innerface of the door, by means of pins 23 and 23 connecting the said arms and plates, said pins passing through horizontally slotted openings 24: and 24; in the door.

Pivotally supported on the face of the door alongside the bar 5 is a gravity dog 25, the adjacent edge of the bar 5 being formed with a notch 26, into which notch. thelower end of the dog drops when the handle 16 is turned to bring the bar 5 into relatively lowered position with the door, with the locking plates indrawn. I provide enough play of the parts so that with the point of the dog in looking position in the notch 26 the handle 16 may be oppositely turned toward the dog 25 to actuate the parts enough to shove the locking plates outwardly far enough to keep the door from swinging outwardly through the door opening.

As shown'in Fig. 1 the actuating parts are covered by an outer plate 27 formed with an opening 28 to give access to the bandle 16 and with a slotted opening 29 through which the out-turned end 30 of the dog 25 projects. Thus with the dog locked in engagement with the bar 5, the handle 16 can only be actuated to cause the locking plates to be forced outwardly sufficiently to engage with the sides of the door way and hold the door from swinging therethrough, this amount of actuation, as already pointed out, being permitted by the amount of looseness which exists between the parts. It will be evident that as the dog is released and the parts further actuated to force the pins 20 outwardly the cam action between the plate 14 and bar 5 will lower the door with reference to said bar causing the bottom of the door to come into engagement with the threshold of the door way.

I claim:

1. In combination with a grain car and its door opening, rails supported along the inner side wall of the car adjacent to the top of the door opening, a bracket slidably supported upon said rails, a door having pivotal and vertically slidable support upon said bracket, outwardly projecting locking pins slidably supported upon the face of the door, and actuating mechanism supported upon the door for forcing said door downwardly into contact with the threshold and said pins outwardly into engagement with the sides of the door opening.

2. In combination with a grain car and its door opening, rails supported along the inner side wall of the car adjacent to the top of the door opening, a bracket slidably supported upon said rails, a door having pivotal and vertically slidable support upon said bracket, outwardly projecting locking pins slidably supported upon the face of the door, outwardly slidable plates supported upon the inner face of the door, and mechanism supported upon the door and actuatable to force said door downwardly against the threshold and said pins and plates outwardly to make contact respectively with the sides of the door opening and with the inner wall of the car along the door opening.

3. In combination with a grain car and its door opening, rails supported along the inner wall of the car adjacent to the top of the door opening, a door having vertically and horizontally slidable pivotal support upon said rails, outwardly slidable pins and platessupported upon the door, means for shoving said door downwardly into contact with the threshold and said pins and plates outwardly into contact with the sides of the door opening, and means locking said actuating means against more than a partial movement of said parts, for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
